Definitions

  • the invention relates to a device for compensating for pressure surges in the event of possible dust or gas explosions in closed systems, such as silos, pipes or the like has a flat outer surface, the walls forming the hinged cover being formed from thin metal sheets.
  • explosion flaps are known in downstream elements, such as filters or the like.
  • an explosion flap is essentially rectangular in shape with edge frames formed from profile iron, between which one Cover surface is provided as a hollow body made of two sheets.
  • This lid construction is comparatively heavy and cannot be designed as a plate-shaped round lid in the construction shown.
  • the object of the invention is to make such a hinged lid even lighter, so that it can be moved by the pressure wave in particular in even greater speed without being destroyed in the open position.
  • this object is achieved according to the invention in that the inner surface of the hinged cover opposite the flat outer surface and facing the interior of the outlet connector is curved as a spherical cap, the walls surrounding the cavity of the hinged cover are formed from thin light metal sheets and the inner sheet is equipped with a fastening edge which enables spot welding to the outer sheet, the fastening edge being provided all around with a sealing web is.
  • the design features according to the invention serve in a special way to optimize such a lid construction, in particular the lightweight construction which is the focus here, while at the same time being resistant to the forces acting on a corresponding lid in extreme cases.
  • the spherical cap-like design of the inner surface of the lid serves for stability and resistance to the impinging pressure waves, the thin light metal sheets bring about a considerable saving in weight and the edge design through these sheets themselves lead to the necessary stability without additional edge-forming profiles having to be provided.
  • the cavity of the hinged lid can be expediently filled with an insulating foam
  • the lid can additionally be equipped with a hinge plate and / or with a heating device and the like.
  • the hinged lid e.g. riveted or glued to one another with the interposition of a plastic insulating ring. It is particularly useful if the formation of condensation water is to be avoided.
  • the collecting plate is provided with a clamping spring tongue for fixing the opened cover in the event of opening, in order to pivot it back to prevent the lid in an uncontrolled manner. It is also achieved by the fixation in the open position after an explosion that this malfunction is visually recognizable from the outside through the opened and kept open cover.
  • the device generally designated 1 in the figures, has an outlet connection 2 which can be flanged, for example, to a relief pipe section of a pipeline.
  • This outlet port 2 is equipped with a hinged lid, generally designated 3, which is about a pivot axis 4 in the event of pressurization, for example by an explosion or deflagration in the pipeline, against a spring-loaded catch plate 5, which is only shown in regions in FIG. 1, can be swung open.
  • the hinged lid 3 is designed as a hollow body, i.e. it has a flat outer surface 6, e.g. made of 2 mm thick aluminum sheet, and a spherically domed inner surface 7, the cavity designated 8 between the inner surface 7 and outer surface 8 being foamed with a plastic foam 9.
  • the outer surface 6 and the inner surface 7 can be connected to one another by point welding at the contact line 10, which is also shown in dashed lines in FIG are glued together, which is not shown.
  • the sheet metal forming the inner surface 7 has a sealing web 11 which engages around the outside of the outlet nozzle 2 and which engages from above into an annular seal 12 which surrounds the outlet nozzle 2 on the outside.
  • the hinged cover 3 is provided with a hinge plate that overlaps it in some areas 13 provided, which can also be designed at least in regions as a pocket, in which the hinged lid 3 engages.
  • the collecting plate 5 is resiliently mounted by means of spiral springs 14, the possibility of equipping the hinged cover 3 with an additional heating device is not shown in detail.
  • the hinged lid 3 is shown in different positions relative to the spring-loaded collecting plate 5.
  • the spring-loaded collecting plate 5 in the example shown is equipped in the upper region with a clamping spring tongue 15 which cooperates with the edge 11 of the cover 3 in such a way that the edge 11 can pivot under the tongue 15 by a nose-like approach 16 but can be fixed in the open position.
  • FIGS. 3a to 3c The different pivot positions are shown in FIGS. 3a to 3c, the cover 3 in FIG. 3a being still comparatively far away from the collecting plate 5, the pivoting direction being indicated by an arrow 17.
  • Fig. 3b the lid 3 is shown shortly before contact with the clamping spring tongue 15, while in Fig. 3c the locking position is, that is, the lid 3 is fixed to the collecting plate 5 in the open position by the clamping spring tongue 15 or the clamping projection 16.
